Supposedly on par with HD 4870, GTS 250 cards
member on mymypc.com posted several images and benches of AMD's upcoming HD 5750, and the new cards looks pretty nice.
The HD 5750 reportedly has 1120 stream processors and 56 texture units.
Like the 5800 series, it packs GDDR5 memory, but on a 128-bit bus. Two
5700 cards are expected to appear, the $199 HD 5770 and the $149 HD
5750. They should replace current generation HD 4890 and HD 4870 cards,
and they should compete with Nvidia's GTS250, GTX260 cards, as well as
upcoming DX11 Nvidia hardware.
Anyway, in synthetic tests the HD 5750 manages to beat both the HD 4850
and the GTS 250, although by a rather tight margin. According to GPU-Z,
the HD 5750's core clock is 625MHz, while memory is clocked at a
surprisingly high 1150MHz, offering 73.6GB/s of bandwidth. We're really
not sure about the memory spec, this seems a bit too fast, so take these numbers with a grain of
